ExtUtils::CppGuess(3pm) User Contributed Perl Documentation ExtUtils::CppGuess(3pm)

NAME

ExtUtils::CppGuess - guess C++ compiler and flags

SYNOPSIS

With Extutils::MakeMaker: 

    use ExtUtils::CppGuess;

    my $guess = ExtUtils::CppGuess->new;

    WriteMakefile
      ( # MakeMaker args,
        $guess->makemaker_options,
        );

With Module::Build:

    my $guess = ExtUtils::CppGuess->new;

    my $build = Module::Build->new
      ( # Module::Build arguments
        $guess->module_build_options,
        );
    $build->create_build_script;

DESCRIPTION

"ExtUtils::CppGuess" attempts to guess the system's C++ compiler that is compatible with the C compiler that your perl was built with.

It can generate the necessary options to the Module::Build constructor or to ExtUtils::MakeMaker's "WriteMakefile" function.

METHODS

new

Creates a new "ExtUtils::CppGuess" object. Takes the path to the C compiler as the "cc" argument, but falls back to the value of $Config{cc}, which should be what you want anyway.

You can specify "extra_compiler_flags" and "extra_linker_flags" (as strings) which will be merged in with the auto-detected ones.

module_build_options

Returns the correct options to the constructor of "Module::Build". These are: 

    extra_compiler_flags
    extra_linker_flags

makemaker_options

Returns the correct options to the "WriteMakefile" function of "ExtUtils::MakeMaker". These are: 

    CCFLAGS
    dynamic_lib => { OTHERLDFLAGS => ... }

If you specify the extra compiler or linker flags in the constructor, they'll be merged into "CCFLAGS" or "OTHERLDFLAGS" respectively.

is_gcc

Returns true if the detected compiler is in the gcc family.

is_msvc

Returns true if the detected compiler is in the MS VC family.

add_extra_compiler_flags

Takes a string as argument that is added to the string of extra compiler flags.

add_extra_linker_flags

Takes a string as argument that is added to the string of extra linker flags.
